I think they mean FSpOpenDF (https://dev.os9.ca/techpubs/mac/Files/Files-53.html#HEADING5...), a (relatively) late addition to the Mac API.
replyThe FSSpec calls added in System 7 are mostly new interfaces to existing File Manager functionality. There's an actual high-level `OpenDF()` call, which is like `FSOpen()` except that it won't try to open a driver when the name begins with `.`.
replySome applications call `OpenDF()` without checking its availability, but fall back to `FSOpen()` or equivalent if `OpenDF()` returns `paramErr`, which is what the parent is witnessing. See `68k/modules/ams-fs/Files.cc` in the `metamage_1` repo.
If the error message is confusing people, maybe it's time to implement `OpenDF()` for real.
That, or add this information to the error message: OpenDF not implemented, falling back to FSOpen
replyAh, yes, the two front ends I haven't touched in years. This should be fun. :-)
replyYou clipped the part that said "Starting VNC server on 127.0.0.1:5900". Did you try connecting a VNC client?
OpenDF is a MacOS toolbox call (which is apparently not implemented)
replyStrange it errors out on given that I assume the thing does run elsewhere. The X11 version sometimes shows the opening screen but any attempt at interaction leads to the mentioned error. The VLC version shows the error directly.
replyAny interaction with the Welcome application terminates it. Try setting AMS_APPNAME=Tic-tac-toe in the environment, or AMS_APPNAME="Nyanochrome Cat".
replyYes, that works, the tic-tac-toe thing appears and remains even though the error message regarding OpenDF is shown. In other words that error message can be ignored, at least as long as whatever is in AMS_APPNAME does not require whatever OpenDF provides.
